Modbus supported hardware
The Modbus driver is the extension of the runtime that
contains the protocol specific logic to communicate with
the devices that support the Modbus protocol. Communication
support is provided for Modbus devices through either
Ethernet TCP/IP, Serial RS-232, or Serial RS-485.
Supported devices and communication interfaces
The Modbus driver has been tested interacting with the following devices.
Communication with the following devices was performed over an Ethernet TCP/IP connection.

The driver will communicate to vendor devices that
implement the Modbus protocol as defined in the Modbus
Application Protocol Specification, V1.1b. The driver
provides the Read Only and Read/Write capabilities to the
following register types:
- Coils - Read/Write
- Discrete Inputs - Read Only
- Input Registers - Read Only
- Holding Registers - Read/Write
